"The hack of Dutch certificate authority DigiNotar already bore many similarities to the break-in earlier this year that occurred at a reseller for CA Comodo. Bogus certificates were issued for webmail systems, which were in turn used to intercept Web traffic in Iran. Another similiarity has since emerged: the perpetrator of the earlier attacks is claiming responsibility for the DigiNotar break-in. Calling himself ComodoHacker, the hacker claims that DigiNotar is not the only certificate authority he has broken into. He says that he has broken into GlobalSign, and a further four more CAs that he won't name. He also claimed that at one time he had access to StartCom."
